This patchet's main motivation is to account for a corner case in which
the read constrains imposed by the device are not respected by pblk. In
the process, it also refactors parts of the read ring buffer to simplify
creation/deletion operations and improve readability.

Note that the checkpatch warnings on missing comments for memory
barriers are false positives.

The code is also available in the for-4.20/pblk branch in the OCSSD github
project.

Thanks,
Javier
